Files through the air.
Literally.
Flipbook turns any file into a flickering strip of QR codes. Show it on one screen, point another device's camera at it, and the bytes cross over. No Wi‑Fi, no cable, no account.
Typical: open Send on your Mac, Receive on your iPhone. Hold the phone 20–40 cm from the screen.

Every frame carries a header, so the receiver can start mid‑stream and missed frames come round again on the next loop. Parity frames patch single drops without waiting.
Point it at the flickering code. Fill the box.

Scanner settings & tips
- Keep the whole code inside the dashed box and hold still. Closer is better as long as it fits.
- If the speed reads 0, the phone is probably too far, or the screen is too bright — drop the sender's brightness a notch.
- If frames keep getting missed, slow the sender down or lower its bytes per frame.
